Robert Pattinson and girlfriend FKA twigs are reportedly getting serious about their relationship and are eager to take it to the next level.

According to a report in Hollywood Life, the 28-year-old Remember Me actor and the 26-year-old singer, whose real name is Tahliah Debrett Barnett, are talking about their future together.

"Rob and Tahliah talk about kids all the time. They both agree that they want lots of kids and they want to travel extensively with them to teach them about the world and other cultures," a source said.

"They like to play name games, like what's the most interesting and meaningful name they can come up with for their future kids. They're not in a rush. They are still young and really into their careers, but love talking about the big family they will one day create together," the insider added.

Pattinson is very open about his relationship with twigs, unlike with his former girlfriend Kristen Stewart.

In 2012, Pattinson ended his relationship with Stewart, his Twilight co-star and girlfriend of four years, after it was confirmed that she cheated on him with British director Rupert Sanders.

The 24-year-old Camp X-Ray star and Sanders, who worked together on Snow White And The Huntsman, were photographed kissing in the Hollywood hills.

Meanwhile, it was previously reported that Pattinson and twigs are wearing promise rings.

"They picked the rings out together. Rob wanted to give Tahliah a promise ring over the holidays, but couldn't find the right one so he held off," another source told the website. "They had been looking at rings together since the beginning of the year. It's like a pre-engagement ring. Very authentic and one of a kind."
